Beit known thatwe, WILLIAM P. THOMSON, of Lansdowne, Delaware county, and SAMUEL G. THOMSON, of Altoona, Blair county, Penn-' sylvania, have invented a new and useful Railoint, of which the following is a full, clear, and exact description, reference being had to .bar and an end view of the bars in place; and

' Figs. 6rand 7 are views similar to Figs. land 5, showing another form of our invention.

Our invention relates to the angle-bars used for suspended joints of railway railsthat is,

joints in which the meeting'ends of the rails the ties ateaoh si e of the rail-joint. The

angle-bars at opposite sides of the joint are similar in character and each consists of an upper vertically extending portion 4, thehead 5 of'which fitsiunder the head of the rail, this portion merging into. the intermediate sloping portion 6, which fitson the baseflange of the rail. The portion Gisinclined outwardly and downwardly to a 'point beyond the edge'of the rail-base and in this formv merges into a flange which is bent inwardly at a sharp angle in itsportion 7 I and has at its inner end a depending vertical portion 8.] It will be noted that theportion 7 extends in v wardly between the horizontal at an angle of fortyfive degrees thereto. It will further be noted that avertical plane passing through .the outer edge, of-. the 'railhead extends through the intermediate portion of the part .Q'Of the angle-barand preferably'adjacent to.

the center of gravity of this portion 4' and similar to Fig. '1, except that the depending that the center-of gravity of the entire anglebar is brought in close to theeenter of gravity of the rail, thus decreasing thetendency v of'the angle-bars to spread outwardly under. the load. The depending flanges of theangle-bars are freethat is, they are not connected to each other and are free to spring under strains. The parts 4 and 6 of the angle-bar are extended longitudinally over the ties at the ends of the joint, w'hile the depending flange portion isv cut away at the ends, so tha't it will fit down between the ties; In using these angle-bars the'angles are bolted through the rail ends in'the ordinary manner, the free flanges projecting below the base of the" rail. The advantages of this construction are numerous. By moving the upper portion of the angle-bar inwardlyfrom.

No. 586,804, the portion 6 is rendered of sufficient width to give plenty of room for the spike-heads and for driving the same without striking the nuts or bolt-heads, thus avoiding, the use .of a rib such as shown in the Thomson patent, No. 586,804. This also moves the center of gravity of the angle-bar inwardly toward the center of gravity of the rail; The sharp inward bending of the flange also carries this centerof gravity-inwardly without contacting with the-bottom of-the rail-base.

In Figs. 4 and 5 we show a form similar to that of Figs. 1, 2, and 3, except that the flange 7" projectsvertical'ly instead of being bent inwardly. In Figs. 6 and 7 we show a form portion 8 of the flange is removed, the bar being otherwise the same as that of Figs. 1, 2, and 3.- 'In each ofv these casesthe'flange is cut ofi at the ends -and depends between the ties, while 'the'ends of the bar proper projectv .9 Changes may be made in'the form andar- 'rangernent oftheangle-bar and flange ,withover thetie's, but do not contact with them.

out departing from our invention.

Weelaim 1. In a suspended rail joint, an angle bar having its end portions arranged toex'tend ".over the ties, said portions being wholly above the lower face of the rail-base, and provided the position'shown in-theThomson patent,

having its end flange portions cut away,'its

with an intermediate depending flange arranged to extend between the ties and free to spring under the load, the bar having an up pen-nead 'and an intermediate vertically-extending web portion extendingdown from the bar being of sufiicient width to provide for the spike-head without a projecting rib, the 20 intermediate base portion of the angle-bar sloping outwardly and downwardly and fitting on the upper face of the rail-base;-substantially'as described.v

3. In a suspended rail-joint-an angle bar having-its end portions arranged to extend over the ti'es, said portions being wholly above the lower face-of the rail-base, and providedwith an intermediate depending flangearranged to extend between the ties and free to spring under the load, the bar 'being arranged so that a vertical planeat the side of the rail-head interse'cts the intermediate portion of its'upper web,'the intermediate base 1 portion of the angle-bar sloping outwardly anddownwardly'and fitting on. the upper face,

of the rail-base, said intermediate base portion being of suflicient width to provide for the spike-head without a projectingrib; sub:

'stantially as described.

4. In a suspended rail-joint, an angle-bar remaining end portions being arranged to extend over the ties,.such remaining portions being wholly above the lower face of the railbase, the intermediate base portion of: the bar sloping outwardly and downwardly and fitting on the upper face of the rail-base, said portion being of suflicient width to provide'for spike-heads without a projecting rib and hav- 5 ing an inwardly-projecting depending flange between the ties, said flange. being free to spring under the load; substantially as described.-

5. In a suspended rail-joint, an angle-bar having a free depending flange extending in.-

ward'ly beneath the rail-base at an angle substantially less than forty-five degrees, and free to spring under the load; substantiallyas described.

6. In a suspended rail-joint an angle-bar having a free depending flange extendingat an inward angle beneath the rail-base and having at its inner end a depending.verticallyex' tending portion; substantially as described.

7. In a suspended rail-joint, an angle-bar arranged to extend over the ties and having a free depending flange in its intermediate portion beneath the meeting ends of the rails, the

ends of, the'flange being cut away to n1'ake room forthe ties, said flange projecting at an inward angle substantially less than fortyfive degrees, and free to spring under the load;

substantially as described.

8. In a suspended rail-joint, an angle-bar having its end portions arranged to-e'xtend over the ties, and provided with an intermediated'epending flange arranged between the ties and. free to spring under the load, the base portion of the bar being of suificient width to provide for the spike-head without a project.- ing rib, the intermediate base portion of the angle-ban sloping outwardly and downwardly and fitting on the upper face of the rail-base; substantially as described. Y

9, In a suspended rail-'oint, an angle-bar having its end-portions arrangedtoextend over the ties, and provided with an intermediate depending flange arranged between the ties and free to spring under'the load, said flange projecting inwardly at an angle substantially less than forty-five degrees, the in-.

termediate base portion of the angle-bar sloping outwardly and downwardly and fitting on the upper face of the rail-base; substantially as described. V v f In testimony whereof we have hereunto set our hands. Y 1 I WILLIAM P. THOMSON.
